Tutorial // Erasers

The first tutorial I’m redoing is probably the most basic, because… baby steps!  I got a lot of great responses when I posted this initially, so I figured it really did help a few of you guys.

Erasers

For those of you who are Photoshop beginners, you may be unaware of the somewhat hidden options that can be found under most tools.  The easiest way to access these (if you aren’t familiar with how to customize your keyboard shortcuts) is to right click your tool icon.  Other variations of that tool should now pop up, as shown above.

As you can see, the Eraser Tool is not horribly effective if you’re trying to take the green (or whichever color) out of hair.  It definitely has its uses though, for instance – if I’m planning on redrawing a limb from scratch, this is my go-to.

Background Eraser

This tool is by far my favorite for removing green from images.  I don’t typically edit pictures with backgrounds, so this makes things much easier for me.  Remember to pay attention to a few things:

Background Eraser Preferences

Depending on the contrast between whatever color you’re trying to erase and the focal point of your image – you’ll need to adjust your tolerance.  The higher the tolerance, the greater your color range will be.  There’s also a ‘Protect Foreground Color’ feature that comes in handy a lot of the time; having this checked will ensure whichever color you have chosen as your foreground color will be excluded (for the most part) from the Background Eraser – just remember to keep your crosshairs on the color you want to eliminate.  In the example above, I selected my avatar’s hair color (using alt+click) so that I wouldn’t have to worry about any of the brown tones being erased accidentally.

Magic Eraser

Magic Eraser

The Magic Eraser basically erases chunks that fall into your tolerance range.  As you can see, it eliminated most of the green surrounding my avatar, but once it comes into contact with a color outside of your tolerance range (the brown in my hair, peach in my skin, etc.) it stops; using the Magic Eraser tool will generally take you several clicks, whereas normally the Background Eraser tool should only take a few.


I hope this was helpful for anyone who took the time to read through the whole thing!  Please let me know if you need any clarification, or are still confused about one of these tools.
